' PADLOCK.

SPECIFICATION forming part of Letters Patent No. 470,268, dated March 8,1892. Application filed January 4, 1892- Serial No. 416,933- (No model.)I

To all whom it may concern.-

Be it known that I, WILLIAM F. Tnonsr, a

citizen of the United States, residing in Lanca'ster, in the county ofLancasterand State of Pennsylvania, have invented certain Improvementsin Padlocks, of which the following is a specification. K

My invention relates to that class of padlocks in which the long arm ofa U-shaped hasp or shackle is held in place bytumblersextendinglongitudinally between the top and notched swinging armand the other arm pivoted in the case, of a tumbler or tumblersextending between the top and bottom of the case and constructed toengage the notched arm, and a tongue formed on the pivoted arm of theshackle, adapted to engage said tumbler or tumblers when disconnectedfrom the swinging arm of the shackle and hold it or them in position toagain engage said swinging arm.

' My invention consists, also, in the combination, with a U-shaped haspor shackle having notches cut in opposite sides of the swlnging armthereof and the other arm pivoted in the case, of two tumblers extendingbetween the top and bottom of the case and having wings constructed toengage said notches and a tongue formed on the pivoted end of theshackle adapted to enter between the tumblers when theyare disengagedfrom theswinging arm of the shackle and hold them apart until saidswinging arm is again inserted between said wings.

My invention consists, finally, 1n the combination, with a pivotedU-shaped shackle having notches cut in opposite sides of the swingingarm and the other arm pivoted 1n the case, and tumblers extendingbetween the top and bottom of the case and constructed to engage saidnotches, of other details of construction, as hereinafter described, andspecifically set forth in the claims.

My invention is fully illustrated in the accompanying drawings, inwhich- Figure l is a side elevation of my padlock, and Fig. 2 an edgeview of the same. Fig. 3 is a perspective interior view of the sectionof the case with which the pivots are formed, showing the operatingmechanism in place and the swinging arm of the shackle engaged by thetumblers; and Fig; 4, a similar view, but showing the swinging armdisengaged from the tumblers. Fig. 5 is a perspective interior view ofthe section of the case with which the pivots are formed, the operatingparts and the shackle being removed; and

Fig. 6, a similar View of the other or closing section. Fig. 7 is aviewsimilar to that shown in Fig. 4:,but showing the parts more from theside. Fig. 8 is a perspective view of the spring-tumblers detached fromthe case. Fig. 9 is an edge View of the pivotal connection of theshackle with the case. I

Similarlettersindicatelikeparts throughout the several views.

The lock-case is divided vertically and longitudinally into two sectionsA and A, as shown in Fig. 2. On the inner face of the side of section Athere are formed rivet pins a and a, the pin a serving as a pivot tosecure the fast end of the shackleB in the case.

Upon the springing end of the shackle there is a reduced extension I),in the opposite sides of which there are recesses Z), adapted to beengaged by the tumblers to be hereinafter described, and on the fast endthere is formed a tongue 6 constructed to enter between the tumblers asthe shackle is opened and hold them apart to allow the said swinging endto be again inserted between them. From near the bottom of the case andextending toward the top thereof there is a keyway F, consisting of ablock cast on the center of the inner face of the side of section A andhaving a semicircular groove cut inits outer face, and between the-upperend of the keyway and the top of said section there is located a shortvertical rib g.

The tumblers E extend longitudinally from the bottom to the top of thecase and have wings e projecting from the sides of their vibrating ends,adapted to engage the recesses Z) in the end I) of the shackle. Thesetumblers are formed integral with each other at the bottom and are madeof a single piece of spring metal, thus combining in the same part thefunctions of the tumblers and the spring, which forces them intoengagement with the notches in the swinging arm of the shackle. Thelower or connecting part c of the tumblers is flattened and the centralportions of said tumblers are cut away from near their vibrating edgesto said part c, inserted between the keyway F and the bottom of thecase, upon which it rests and to which it is secured by riveting down ashoulder formed on one side of the keyway by the slot f. In the centerof the connecting part 6 there is a winged key-hole e that registerswith a similar opening in-the bottom of the case. In the middle of thetop plates of the sections A A there is an inward extension having inits meeting edges arccess to, which, when said sections are united,register with each other and form a circular indentation that receivesand stcadies the inner end of the key. The closing section A is providedwith rivet-holes a and a engaged by the rivetpins a and a, respectively.On the inner face of this section there is also formed a vertical ribII, which, when the sections are united, is located somewhat inside ofone of the edges of the kcywayand serves as a guide for the key. letweenthe upper end of this key-guide and the top plate of the section thereis a horizontal ward G located, the position of which varies indifferent locks, as is usual with different locks of the same class, toprevent the key of one lock being used with all the others. Vhen thetumblers are in place in the case, the part e rests between the keyway Fand the bottom plate of the case, the said keyway projecting through theopening in the adjacent tumbler E. The bar a", connecting the sides ofthat tumbler at its vibrating end, is bent inward, as shown in Fig. 3,that it may be the more readily engaged by the corresponding ward of thekey, and when the wings a are engaged with the shackle this bar restsupon the rib g, that the curve therein may be preserved. Below therivet-pin a, in section A, there is a stud (Z, around which is coiled aspring D, an end of which bears against the outer face of the tongue bthe other end (1 resting against the edge wall of the ease, as seen inFigs. 3 and at. \Vhen the tumblers are disengaged from the long arm ofthe shackle this spring D forces the tongue 11 between the tumblers Eand opens said shackle, the length of the reduced extension 1) below therecesses band that of the tongue 1) being such that the end of saidtongue is inserted between the tumblers before the extension 6 isentirely freed from them.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is

1. In a padlock, the combination, with a shackle having the fast armpivoted in the case and the swinging arm constructed to be engaged by atumbler, of a spring-tumblerextending between the top and bottom of thecase and having the upper end adapted to engage the swinging arm of theshackle, and a tongue formed on the pivoted arm of said shackle, adaptedto engage said tumbler when disconnected from the swinging arm of theshackle and hold it in position to again engage said swinging arm,substantially as and for the purpose specified.
